INTERNAL COMBUSTION ENGINE WATER SYSTEM CLEANER Original Filed July 27, 1935 2 Sheets-Sheet 2 Patented Oct. 12, 1937 UNITED STATES INTERNAL COMBUSTION ENGINE WATER SYSTEM CLEANER George E. Baucom and Kelso M. Banks, Raleigh, N. C.; said Banks assignor to Harry H AHearn Application July 27, 1935, Serial No. 33.588 Renewed August 11, 1937 1 Claim;

'I'his invention relates to cleaning apparatus for water systemsw on internal combustion engines.

The primary object of the invention is to clean and strain all foreign particles from the water used in cooling internal combustion engines so as to eliminate corrosion in the water jackets of the cylinders of the engine.

Another feature ofthe present invention is to 'l0 place a cleaner in a by-pass in the water circulating system so that only a portion of the volume of the circulating water is being cleaned while the remaining portion is circulating.

Further objects of the invention are to provide a device of the character referred to that is strong, compact and durable, thoroughly reliable for its intended purpose, very simple and easy to install in the conventional water circulating system and comparatively inexpensive to manufacture and operate.

With the foregoing and other objects in View the invention consists 'of a novel construction, combination and arrangement of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings, wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations, and modications may be resorted to without d eparting from the spirit of the claims hereunto ap- 30 pended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a fragmentary section through the forward portion of ran automobile showing the internal combustion engine in side elevation and an adaptation therewith of a cleaning device in accordance with the present invention.

Figure 2 is a detailed vertical section through the cleaning tank removed from the water circulating system.

Figure 3 is a horizontal section taken substan-V tially on line 3--3 of Figure 2.

Figure 4 is a fragmentary top plan view of the cleaning tank.

Referring to the drawings in detail, A indicates generally an automobile carrying an internal combustion engine B in the forward end thereof. As is customary in the construction of automobiles the radiator 5 is supported on the forward end of the automobile in front of the internal combustion engine B.

The cleaner of the present invention is adapted for installation in a pressure Water circulating system which pressure is developed by a conventional pump 6 carried on the side of the internal combustion engine. From the bottom of the radiator 5 the water is withdrawn through the con-v ductor 'I into the bottom of the pump and forced out of the top of the pump through the. conduc- 5 tor 8 into the side of the internal combustion engine where it circulates through the cylinders and passes out of the top of the engine through `the conductor 9 into the top of the radiator.

In the installation of the cleaner in accordance 10 with the present invention there is a branch conductor I0 connected with the conductor 8 which extends into the bottom -of the cleaning tank C and this cleaning tank C is carried by the side Wall of the internal combustion ,engine on a 15 bracket II secured thereto by means of bolts I2. From the top of the cleaning tank C there extends the outlet conductor I3 which is connected on its outer end to the conductor 9 that leads into the radiator 5. It will thus be seen that a por- 20 tion of the water circulated under pressure by the pump 6 is by-passed through conductor I0 into tank C and out'conductor I3 whereupon only a portion of the volume of Water being circulated ris passed through the cleaner. 25

The cleaning tank C of the present invention is preferably cylindrical in shape and formed of metal. The side walls of the tank are indicated at I4 and the vbottom wall I5 is in the shape of a basin. In the center of the bottom Wall I5 is an 30 opening about which is a depending flange I6 through which the upper end of conductor I0 extends. The inner end of conductor I0 projects above the bottom wall I5 and into the bottom of the chamber I'I in the tank. To one side of the 35 conductor I0 there is formed a depending nipple I8 into which is threaded the petcock I9 for the purpose of draining the tank.

At the upper end of the sidewalls I4 is an inset horizontal iiange 20. Secured to this flange 40 is a cover plate 2I bolted vthereto by means of the bolts 22. In the center of cover plate 2l is a flange 23 that depends into the interior of the` (tank. Connected to the iiange 23 is the inner end of the conductor I3 that forms the outlet to 45 the tank. I

A circular basket or container 24 extends into the chamber I'I about one-half the height of the tank. Ihis container 24 is formed of reticulated 50 material such as heavy copper screening. On the upper end of the container 24, it has a lateral flange 25 secured between the upper face of flange 20 and the bottom of the cover plate 2| whereby it is clamped in position. The shanks 55 of the bolt 22 extend through openings in the ange 25.

In the basket or container 24 there is placed mineral filtering material 26 such as sand, gravel, or other filtering material in the amorphous condition or it may be in a solid cake. It is to be understood that the filtering material 26 substantially iills the container 24 with the exception that the central strainer 21 in the form of a porous shell extends into the filtering material. The strainer 21 is disposed concentric with respect to the container 24 and is likewise formed of ne reticulated material such as copper screening. Strainer 21 is tubular in shape and closed at its free inner end, while the upper end thereof fits over the inner end of outlet conductor i3.

As a portion of the cooling water is by-passed through conductor IIJ and into the chamber l1 of the tank it flows through the filtering material 26 in the container 24. The ltering material 26 removes all solid particles of material in the water and holds the particles mechanically. 'Any particles that escape through the filtering material is impeded by the walls of the screen 21, which wallspare of a finer niesh than the walls of the container 24. It will thus be seen that all particles in the Water are removed from the water in the cooling system thereby eliminating the corrosion in the water jackets in the engine.

Having thus described the invention, what is claimed as new is:

A strainer comprising a tank, said tank being provided with a top, a reticulated basket supported by the said top and depending into the said tank, said basket terminating short of the bottom of said tank, ltering material in the basket, a pipe extending into the tank below the basket, said top being provided with an opening,

said top being provided with a depending annular flange at the said opening therein, a cylindrical-shaped straining element embedded in the ltering material and having one end abutting the said iiange, the other end terminating short of the bottom of the basket, and a second pipe extending through the opening of the top and snugly tted in the said flange and cylindrical strainer.
